Customer is important factor in software development process.
Customer wants some products and is
having bunch of requirement of that specific product.
So business analyst will collect all
requirements from the customer.
After that business analyst will
create document and send it to the developer and testers.
Then developer develops application
as per the customer requirement.
Then developer will send that product
to the tester for testing.
Then tester will test that application in detail (positively
as well as negatively).
Positive testing :-
Positive
testing is nothing but we have to
provide correct input to the application.
Ex.
If there is mobile field, in india mobile number are of 10 digit, then tester
check the functionality by entering 10 digits number, whether it works or not.
Negative testing :-
Negative
testing is nothing but we have to provide
incorrect things or we have to
perform negative operations on the functionality.
Ex. If there is mobile field, the number should not
accept 9 digit or less and more than 10 digites. Tester checkes system by
entering less or more than 10 number in field.
When testing is completed
and application is working properly as per the customers’ requirements then we
have to deliver that application to the customer.
